For restocking of your small pond and to reduce the chances of over population from one of them, you could stock single gender fish species. It could be one or several all male bluegill, maybe 1 pumpkinseed, 1 crappie, 1 yellow perch, 1 LMB, 1 SMB, 1 catfish and for added natural foods you could add 50-100+ fathead minnows. Instead of bread to feed your fish you could go to a local fish farm and buy a small amount of fish food to feed your fish to help keep them healthier and growing better. Or You could contact by Private Message any PBoss forum member and they could send you a couple pounds of high quality fish pellets for your feeding of several fish.
See this info in our archives link of how to recognize male & female BG. I think your small pond is a good candiate for growing 20-30 all male BG.
